Anti-Vibration Theory and Technology in Underground Tunnels Shock and Vibration Special Issue on Anti-Vibration Theory and Technology in Underground Tunnels CALL FOR PAPERS With the construction of a transportation network, underground tunnels are Lead Guest Editor undergoing more challenges. One of the most signicant issues is the inuence Zhigang Tao, China University of of vibration load on the stability of support structures. Underground tunnels are Mining and Technology, Beijing, China mainly subjected to blasting vibration and articial disturbance. According to the taozhigang@òâç.net dierence in frequency and amplitude of vibration load, the supporting structure, shallow surrounding rock, and deep surrounding rock of underground tunnels Guest Editors will be damaged and destroyed to dierent extents. If the eective supporting Chun Zhu, China University of Mining reinforcement is not carried out, the surrounding rock may be deformed greatly, even and Technology, Beijing, China inducing rockburst. To improve construction in underground tunnel engineering, zhuchuncumtb@Ôâç.com anti-vibration theory and technology of underground tunnel has become a popular topic of research in underground engineering. Qingxiang Meng, Hohai University, Nanjing, China Currently, the anti-vibration support theory of tunnel surrounding rocks is mainly [email protected] based on yielding, energy absorption, high strength, integrity, and other ideas. Usu- ally, high-strength support structures can maintain the deformation of surrounding Yun Lin, Central South University, rocks, while the energy absorption structure can absorb the energy transmitted by Changsha, China the vibration wave to ensure the stability of surrounding rocks. erefore, many yunlinâÔÞ@csu.edu.cn supporting structures and bolts with large deformation and energy absorption characteristics have become useful. Nowadays, further research has been conducted Yuanchao Zhang, Nagasaki University, to enhance the anti-vibration performance of underground tunnels by carrying out Nagasaki, Japan large deformation energy absorption supporting measures. bb òòÔÀÔýò@ms.nagasaki-u.ac.jp e aim of this Special Issue is to bring together original research and review Submission Deadline articles highlighting the latest theories, advanced monitoring equipment, and recent Friday, â August òýòÔ engineering problems and solutions.

    This article has been accepted for inclusion in a future issue of this journal. Content is final as presented, with the exception of pagination. IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING 1 Time Series Phase Unwrapping Based on Graph Theory and Compressed Sensing Zhang-Feng Ma , Student Member, IEEE,MiJiang , Senior Member, IEEE, Mostafa Khoshmanesh, and Xiao Cheng Abstract— Time Series SAR interferometry (InSAR) interferogram, in which the observations are known modulo- (TS-InSAR) has been widely applied to monitor the crustal 2π [1]–[3]. The main challenge of PU is that it is extremely deformation with centimeter- to millimeter-level accuracy. Phase difficult to, first, distinguish which pixel contains phase cycles, unwrapping (PU) errors have proven to be one of the main sources of bias that hinder achieving such high accuracy. In this and second, how many the cycles are. A certain phase article, a new time series PU approach is developed to improve continuity assumption that the local phase gradient between the unwrapping accuracy. The rationale behind the proposed neighboring points should be smooth and less than π makes method is to first improve the sparse unwrapping by mitigating this problem tractable. the phase gradients in a 2-D network and then correcting the Based on this assumption, Lp-Norm [4] methods such as unwrapping errors in time, based on the triplet phase closure. Rather than the commonly used Delaunay network, we employ least squares, minimum cost flow (MCF) [5], and minimum the all-pairs-shortest-path (APSP) algorithm from graph theory discontinuity [6] attempt to unwrap phases by shrinking the to maximize the temporal coherence of all edges and to approach Euclidean distances or minimizing the difference between the the phase continuity assumption in the 2-D spatial domain.
